Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading.

Change the entires as follows:

Set “network.http.pipelining” to “true”
Set “network.http.proxy.pipelining” to “true”
Set “network.http.pipelining.maxrequests” to some number like 30. You can keep it from 20-30 as you like. The number ’30’ here refers to making requests. So, here it’s 30 requests.

Now the last step, right-click anywhere and select New > Integer. Name it “nglayout.initialpaint.delay” and set its value to “0”. This value is the amount of time the browser waits before it acts on information it receives.

After you are done with everything just restart the browser, if you are a broadband user you’ll see the difference for sure.
